Use the Command Menu to access settings faster

The Command Menu is a faster alternative to accessing many of the settings. In particular, if you remember the name of the settings or even its value but don't remember where the setting is.

To quickly change a setting:

  1. Open the Command Menu.
  2. Start typing the setting's name or its value, select a suggested option, and press Enter.

For example, to set the DevTools UI language to Chinese, type Chinese and select an option.
